The Key West 239FS is a popular center-console boat designed to balance family-friendly features with serious offshore fishing capabilities. For boaters considering this vessel—particularly those venturing into rough seas offshore—the question of its performance in challenging conditions is critical. Whether you’re navigating the choppy waters of Northern Massachusetts or planning a trip across the Gulf Stream, understanding how this 23-foot-9-inch boat handles 3- to 6-foot seas, high winds, and confused wave patterns is essential. This article dives deep into the Key West 239FS’s offshore prowess, drawing from real-world experiences, expert insights, and technical specifications to provide a comprehensive evaluation.
Understanding the Key West 239FS: Design and Build
The Key West 239FS, part of the Family Sportsman series, is a versatile boat built with a focus on durability, fishability, and comfort. Measuring 23 feet 9 inches in length with an 8-foot-6-inch beam, it offers a spacious deck for its size. The hull features a longitudinally stepped design with a variable deadrise—19 degrees at the transom, stepping up to 24 degrees—which enhances its ability to cut through waves while maintaining stability. Weighing approximately 2,900 pounds dry (before accessories and rigging), it’s relatively light for its class, a factor that influences its performance in rough conditions.
Key West employs a “No Wood, No Rot” construction philosophy, using high-quality fiberglass and a foam-filled hull for positive flotation. This ensures the boat remains buoyant even if swamped, a critical safety feature for offshore use. The self-bailing cockpit and optional gull wings (spray shields) further enhance its suitability for wet environments. Power options range from a 200-hp outboard up to a 300-hp Yamaha or Suzuki, with the latter providing ample thrust for tackling tough seas.

Performance in Rough Seas: What Boaters Say
Boaters who regularly take the Key West 239FS offshore offer valuable insights into its capabilities. Many operate in regions like Northern Massachusetts, the Gulf of Mexico, or the Chesapeake Bay, where conditions can shift rapidly from calm to chaotic. Here’s a breakdown of how the 239FS performs in various rough-sea scenarios:
3- to 4-Foot Seas: A Manageable Challenge
In 3- to 4-foot seas with moderate winds (15-20 mph), the Key West 239FS proves competent but not exceptional. Owners report that the boat can handle these conditions safely, particularly with skilled seamanship. The stepped hull helps it plane quickly and maintain speed, while the deep-V design cuts through chop effectively. However, expect a wet ride—especially in short-period waves (less than 6 seconds)—as the lightweight hull tends to bounce rather than plow through.
One boater from Northern Massachusetts, who frequently navigates between Gloucester and Boston, notes that 3-footers with 20-mph winds are common on the return leg. “The 239FS skips along fine if you keep the speed up and trim it right,” he says. “But you’re dodging spray, and it’s not a dry ride unless you’ve got gull wings.” Another Gulf Coast user echoes this: “I’ve trolled in steep 4-footers in the Gulf Stream. It’s safe, but you’re not comfortable—everything gets soaked.”
5- to 6-Foot Seas: Pushing the Limits
When seas escalate to 5 or 6 feet, the Key West 239FS reaches its practical limit for most operators. While the boat can physically handle these conditions—thanks to its foam-filled hull and robust construction—the experience becomes punishing. A Florida-based owner recalls an accidental outing in 6-footers: “I was scared, but the boat did fine at 10 mph, riding the swells. It’s more than I could take, though—I wouldn’t go out in that on purpose.”
Experienced captains emphasize the importance of throttle control and wave timing in such scenarios. The 300-hp engine provides enough power to punch through head seas or maintain control in following seas, but the lightweight design amplifies the pounding. “It’s not about the boat failing,” says a Chesapeake Bay user. “It’s about you getting beat up. Anything over 5 feet, and I’m staying home.”
Confused Seas and Beam Seas: Stability Concerns
Confused seas—where waves come from multiple directions—and beam seas (waves hitting the side) test the 239FS’s stability. The 8-foot-6-inch beam offers decent resistance to rolling, but the boat’s light weight can lead to a rocky ride. “In 3-foot beam seas with 20-mph winds, it’s manageable if you slow down and adjust trim,” reports a user. “But it’s not fun—stuff slides around, and you’re hanging on.”
Following seas present another challenge. The stepped hull can surf down rollers effectively, but careful steering is required to avoid broaching (when the boat turns sideways to the wave). Owners recommend a larger boat, like the Key West 244CC, for those regularly facing such conditions, as its 9-foot beam and heavier hull provide superior stability.
Key Takeaways from Actual Users
- “It’s Not a Deep-V, But It’s Capable”
- Many owners confirm the 239FS can handle 3-4 ft seas but not dryly.
- Gull-wing bow rails help deflect spray, but you will get wet in rough conditions.
- “Bigger is Better, But the 239FS is a Compromise”
- Some argue that stepping up to a 26-footer (like the Key West 263FS or 244CC) would be ideal, but the 239FS is a solid middle ground for those who must trailer and stay under 24 ft.
- “It’s More About Seamanship Than Boat Size”
- Experienced captains say the boat can handle more than the crew can—fatigue sets in faster in rough seas.
Comparing the 239FS to Alternatives
To gauge the 239FS’s offshore prowess, it’s worth comparing it to boats in its size range, such as the Tidewater 230CC and Key West 244CC, as well as smaller (219FS) and larger (26-foot-plus) options.
Key West 239FS vs. Tidewater 230CC
The Tidewater 230CC, with a length of 23 feet and an 8-foot-6-inch beam, is a direct competitor. It features an 18-degree deadrise (less aggressive than the 239FS’s 19/24 degrees) and a slightly heavier hull (around 3,200 lbs dry). In 3- to 4-foot seas, the Tidewater may offer a softer ride due to its weight, but it lacks the stepped hull’s efficiency and speed. “The Tidewater 230 with 300 hp feels sturdier than my old 220,” says a Massachusetts boater, “but the 239FS seems to handle chop better with that hull design.”
| Factor | Key West 239FS | Tidewater 230 |
|---|---|---|
| Hull Design | Stepped V (19°/24°) | Modified V (18°) |
| Ride in Chop | Smoother due to stepped hull | More pounding |
| Beam | 8′ 6″ | 8′ 6″ |
| Weight | ~2,700 lbs (hull) | ~2,900 lbs (hull) |
| Dryness | Better spray deflection | Wetter ride |
| Handling | More agile, better in following seas | Slightly more stable at rest |
Verdict: The Key West 239FS rides better in chop due to its stepped hull, but both boats struggle in true offshore conditions.
Key West 239FS vs. Key West 244CC
The Key West 244CC, at 24 feet 4 inches with a 9-foot beam, is a step up. Its wider stance and deeper hull flare improve stability and dryness in rough seas. Owners who’ve upgraded from the 239FS to the 244CC rave about the difference: “The 244 is a game-changer in 4-footers—less spray, less rocking,” one says. However, the 244CC’s higher cost and trailer width (over 8’6”) may deter some buyers.
Smaller Boats (e.g., Key West 219FS)
The Key West 219FS, at 21 feet 9 inches, is noticeably smaller and lighter (2,400 lbs). It struggles more in 3- to 4-foot seas, lacking the 239FS’s length and power to maintain control. “The 219FS is fine for inshore or calm days,” a user notes, “but offshore in rough stuff, it’s outclassed by the 239.”
Larger Boats (26 Feet and Up)
Boats like the Grady-White 247 (24’7”) or a 26-foot Regulator dwarf the 239FS in rough-water capability. Their heavier hulls (4,000+ lbs) and wider beams (9’+) smooth out 5- to 6-foot seas, offering a drier, more comfortable ride. However, they come with higher price tags and towing complexities, making the 239FS a practical compromise for budget-conscious boaters.
Real-World Scenarios: Northern Massachusetts Case Study
Consider a boater in Northern Massachusetts, operating out of Salem, Marblehead, or Gloucester. The region’s open waters often deliver 2- to 3-foot chop with 15-20 mph winds, escalating to 4- to 6-foot seas on windy afternoons. The 239FS, equipped with a 300-hp engine and gull wings, can manage typical 3-footers within 5-10 miles offshore. Returning home against a head sea, the boat maintains 20-25 mph with proper trimming, though spray is inevitable. In rare 6-foot sneaker waves, slowing to 10 mph and dodging the worst keeps it safe—but not enjoyable.
This aligns with forum feedback: “The 239FS is decent in 3-4 footers if you’re smart about it,” says one user. “Beyond that, it’s survival mode, not boating fun.” For this boater, upgrading from a Tidewater 220 (22’2”) to the 239FS offers a noticeable improvement in ride and stability, though not a dramatic leap.
Technical Factors Influencing Performance
Several design elements dictate how the 239FS fares offshore:
- Hull Design: The stepped, variable-deadrise hull boosts speed and efficiency but sacrifices some softness in heavy chop compared to a constant deep-V.
- Weight: At 2,900 lbs, it’s lighter than competitors like the Grady-White 247 (4,300 lbs), leading to more bounce in rough seas.
- Power: A 300-hp outboard ensures control and quick planing, critical for navigating following seas or punching through waves.
- Beam: The 8’6” width provides decent stability but falls short of the 9’+ beams on larger offshore hulls.
Performance Data (Approximate)
| Condition | Speed | Fuel Efficiency | Ride Quality |
|---|---|---|---|
| Calm (1-2 ft) | 40-43 mph | 3.2-3.5 mpg | Smooth, dry |
| 3-4 ft, 20 mph wind | 20-25 mph | 2.5-3.0 mpg | Wet, bouncy |
| 5-6 ft, 25 mph wind | 10-15 mph | 2.0 mpg | Rough, wet |
Practical Tips for Rough Seas in the 239FS
To maximize the 239FS’s offshore potential, consider these strategies:
- Trim and Tabs: Use trim tabs to keep the bow down in head seas and level in beam seas. Adjust engine trim to reduce pounding.
- Speed Management: Maintain 20-25 mph in 3-4 footers to stay on plane; slow to 10-15 mph in 5-6 footers to ride swells.
- Weight Distribution: Balance passengers and gear to avoid listing or bow-heavy handling.
- Weather Awareness: Avoid short-period waves (<6 seconds) and winds over 20 mph unless prepared for a rough ride.
- Upgrades: Add gull wings for spray protection and a windlass for easier anchoring in choppy conditions.
Is the 239FS Right for You?
The Key West 239FS shines as a versatile, budget-friendly option for offshore boating in moderate conditions—think 3- to 4-foot seas with winds under 20 mph. Its lightweight design, stepped hull, and ample power make it capable within these limits, though it won’t match the comfort or dryness of larger, heavier boats. For Northern Massachusetts boaters facing frequent chop or Gulf Stream anglers tackling 30-50 mile runs, it’s a solid choice if paired with cautious weather planning and skilled handling.
However, if you regularly encounter 5- to 6-foot seas, confused wave patterns, or high winds, the 239FS may leave you wanting. Stepping up to a 244CC or a 26-foot-plus boat offers a significant upgrade in rough-water performance, albeit at a higher cost and towing complexity. For those prioritizing single-engine simplicity, trailerability, and a $50,000-$80,000 price range, the 239FS strikes an impressive balance.

- Nearshore Fishing (5-10 miles out)
- Boaters who trailer and need a manageable size
- Families who want a versatile fishing & cruising boat
Not Ideal For:
- Regular offshore runs in 4+ ft seas
- Those expecting a dry ride in heavy chop
- Anglers who frequently fish in rough inlets
Pros and Cons
| Pros | Cons |
|---|---|
| Affordable and versatile | Wet ride in rough seas |
| Capable in 3-4 ft seas | Limited in 5-6 ft seas |
| Easy to trailer | Less stable in beam seas |
